A method and apparatus for proactively monitoring data center health data to achieve workload management and high availability is provided. The drum washing machine is capable of heating wash water and spraying the heated wash water into a tub and a drum of the washing machine in a phase of high-temperature and high-pressure steam, thereby rapidly soaking clothes in the wash water, improving sterilizing and washing efficiencies of the drum washing machine, and saving wash water and electric energy. The coupler includes a number of radiating elements spaced apart and a switching element. Based, in part, on a flow of media content andor text messages between the members, a determination of a start time andor end time of the spontaneous event is automatically performed. In addition, mapping of event statistics to fuzzy rule premises in the fuzzy inference process may be personalized through the use of user-defined fuzzy sets.
